Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of measuring tools, and particularly relates to a straight plate chain wear measurement device. Background Art
[0002] The chains of coal gangue hoists and dry slag hoists mostly adopt NE50 type straight plate chains (similar to bicycle chains). After being used for a certain period of time, it is necessary to check their wear conditions. If tools such as calipers are used to measure the data placed between two rollers, and then this data is compared with the wear amount to draw a conclusion on whether the chain needs to be replaced.
[0003] In this way, it is time-consuming and laborious, and it is easy to damage the calipers and have large reading errors during measurement, which is inconvenient. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is: how to design a straight plate chain wear measurement device that is convenient for detecting wear conditions.
[0005] The technical solution of the utility model is specifically as follows:
[0006] A straight plate chain wear measurement device includes a measurement straight plate. On one side of the measurement straight plate, there is a mild wear measurement caliper, and on the other side, there is a severe wear measurement caliper. The two measurement claws of the mild wear measurement caliper are the first measurement claw and the second measurement claw, and the two measurement claws of the severe wear measurement caliper are the third measurement claw and the fourth measurement claw. These four measurement claws are respectively fixed at the four corners of the measurement straight plate, and the distance between the first measurement claw and the second measurement claw is less than the distance between the third measurement claw and the fourth measurement claw.
[0007] On both sides of the middle of the measurement straight plate, there are scale readings.
[0008] The measurement straight plate and the four measurement claws are integrally formed.
[0009] Compared with the prior art, the technical effect of the utility model is that the utility model is provided with two groups of measuring rulers, which is convenient for determining the wear condition of the straight plate chain and saves measurement time and energy. Description of the Drawings
[0010] Figure 1 It is a schematic diagram of the utility model.
[0011] Figure 2 It is a schematic diagram of the utility model in use state. Specific Embodiments
[0012] The following details the utility model in conjunction with the drawings and its specific embodiments.
[0013] As Figure 1, A straight plate chain wear measurement device, including a measurement straight plate 10. On one side of the measurement straight plate 10 (the side marked A in the figure), there is a mild wear measurement caliper, and on the other side (the side marked B in the figure), there is a severe wear measurement caliper.
[0014] The two measuring jaws of the mild wear measurement caliper are the first measuring jaw 21 and the second measuring jaw 22, and the two measuring jaws of the severe wear measurement caliper are the third measuring jaw 23 and the fourth measuring jaw 24. These four measuring jaws are respectively fixed at the four corners of the measurement straight plate 10. The distance between the first measuring jaw 21 and the second measuring jaw 22 is less than the distance between the third measuring jaw 23 and the fourth measuring jaw 24.
[0015] For convenient observation, scale readings 11 are provided on both sides of the middle part of the measurement straight plate 10.
[0016] For its own firmness, the measurement straight plate 10 and the four measuring jaws are integrally formed.
[0017] Its working principle is as follows:
[0018] The pitch of the standard NE50 type straight plate chain is 152.4 mm, the roller diameter is 36 mm, and the shortest distance between the outer contours of two adjacent rollers (which is the pitch minus the roller diameter, and this is the data to be measured, hereinafter referred to as the distance to be detected) is 116.4 mm.
[0019] During manufacturing, the distance between the first measuring jaw 21 and the second measuring jaw 22 is set to 118 mm, and the distance between the third measuring jaw 23 and the fourth measuring jaw 24 is set to 125 mm.
[0020] When in use, as Figure 2 , hold the middle part of the measurement straight plate 10 with one hand. Hereinafter, taking one distance to be detected as an example, the following steps are carried out:
[0021] S1. Place the two measuring jaws (the first measuring jaw 21 and the second measuring jaw 22) of the mild wear measurement caliper between two adjacent rollers 91 of the straight plate chain 90 to be measured, and proceed to step S2.
[0022] S2. If the mild wear measurement caliper cannot be inserted, it means the wear amount is extremely small and there is no need to consider replacement, and proceed to step S4; if the mild wear measurement caliper can be inserted, then place the two measuring jaws (the third measuring jaw 23 and the fourth measuring jaw 24) of the severe wear measurement caliper between two adjacent rollers 91 of the straight plate chain 90 to be measured, and proceed to step S3.
[0023] S3. If the heavy wear measuring caliper cannot be inserted, it indicates that there is a certain amount of wear and it can still be used for some time. In this case, there is no need to replace it and proceed to step S4. If the heavy wear measuring caliper can be easily inserted, it indicates that the wear amount is extremely large. In this case, replacement must be carried out and proceed to step S4.
[0024] S4. End.
[0025] Features of this application:
[0026] S1. Using the chain wear amount measuring device, there is no need to read data, it is convenient to use, and it can greatly improve the speed and accuracy of measuring the chain.
[0027] S2. It can be made by cutting steel plates, and the manufacturing of the measuring device is simple.
[0028] S3. Small in size, convenient to carry and use.
[0029] For other content, please refer to the prior art.
[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those skilled in the art, without departing from the overall concept of the present utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present utility model.
